// The Wuffs library ships as a single file - a .h file - which GN does not
|
|
// recognize as something to be compiled, because it ends in .h and not .c or
|
|
// .cpp. Instead, this trivial file is a placeholder .c file that is a BUILD.gn
|
|
// target for the third party Wuffs library.
|
|
//
|
|
// Copy/pasting from the Wuffs .h file's comments:
|
|
//
|
|
// ----
|
|
//
|
|
// Wuffs ships as a "single file C library" or "header file library" as per
|
|
// https://github.com/nothings/stb/blob/master/docs/stb_howto.txt
|
|
//
|
|
// To use that single file as a "foo.c"-like implementation, instead of a
|
|
// "foo.h"-like header, #define WUFFS_IMPLEMENTATION before #include'ing or
|
|
// compiling it.
|
|
//
|
|
// ----
|
|
#define WUFFS_IMPLEMENTATION
|
|
|
|
// Defining the WUFFS_CONFIG__MODULE* macros are optional, but it lets users of
|
|
// Wuffs' .h file whitelist which parts of Wuffs to build. That file contains
|
|
// the entire Wuffs standard library, implementing a variety of codecs and file
|
|
// formats. Without this macro definition, an optimizing compiler or linker may
|
|
// very well discard Wuffs code for unused codecs, but listing the Wuffs
|
|
// modules we use makes that process explicit. Preprocessing means that such
|
|
// code simply isn't compiled.
|
|
//
|
|
// For Skia, we're only interested in particular image codes (e.g. GIF) and
|
|
// their dependencies (e.g. BASE, LZW).
